I have no idea, but listen.
You need to see a psychiatrist about this. It's not good to rely on a regular doctor when it comes to psychiatric conditions, especially hallucinations after Zoloft, which is an anti-depressant (it's ok, sometimes anti-depressants are used to treat anxiety).
You need to talk to your doctor to appoint you to a psychiatrist.
Psychiatrists are experts when it comes to mental health, surely allot more than a general doctor.

I'm praying that your mind will be at peace.
